MATERIAL STRUCTURE CONTROL AS ONE OF THE PERSPECTIVE APPROACHES TO OPTIMIZE
PHYSICAL AND TECHNICAL CHARACTERISTICS OF PIEZOELECTRIC CERAMIC MATERIALS

Abstract

The paper reviews the state of art in the development of new lead-free piezoelectric ceramic materials. Piezoceramic materials are used in a wide field of applications, most of them are based on lead titanate-zirconate. However, modern human health and environmental requirements make necessary the use of alternative lead-free materials. Advantages and drawbacks of perspective piezoceramics are discussed, possible approaches to increase their piezoelectric properties (texturing and template grain growth method) are considered.
